ADN4670 Programmable Low Voltage 1:10 LVDS Clock Driver

The ADN4670 is a low voltage differential signaling (LVDS) clock driver that expands a differential clock input signal to 10 differential clock outputs. The device is programmable using a simple serial interface, so that one of two clock inputs can be selected (CLK0/CLK0 or CLK1/CLK1) and any of the differential outputs (Q0/Q0 to Q9/Q9) can be enabled or disabled (tristated). The ADN4670 is designed for use in 50 Ω transmission line environments. Applications Clock distribution networks

When the enable input EN is high, the device may be pro-grammed by clocking 11 data bits into the shift register. The first 10 bits determine which outputs are enabled (0 = disabled, 1 = enabled), while the 11th bit selects the clock input (0 = CLK0, 1 = CLK1). A 12th clock pulse transfers data from the shift register to the control register.

The ADN4670 is fully specified over the industrial temperature range and is available in a 32-lead LFCSP package.
